@AdamMosheh, because "test" generally implies that the one applying it is trying to learn something. As the One applying these was the Omniscient, that could not have been the purpose.

@Yahu - What do you mean by that? And where does teh Sefer haYetzirah say that?

@AdamMosheh I imagine he means that sometimes kabbalists include Keser instead of Daas, and vice versa. Either way, it's still ten. The quote from Sefer Yetzirah is (I imagine) Ten sefirot of nothingness; ten and not nine, ten and not eleven. Where in Sefer Yetzirah it is probably depends on which edition you have.
